THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 217 
(1) Specimen about 40 ft. long.—Throat, with its furrows, and nearly all of its 
under side, white ; part of under side of flukes white ; pectorals black above, white 
below, the black extending around the edge to the inner side, with an occasional 
blotch of black, and 2 or 3 black rings. 
(2) Specimen about 44 ft. long.—Under side entirely black, except two white 
or marbled patches on the chest, just behind the flippers, and one or two very 
small white spots on belly; navel partly white; pectorals entirely white below, 
above with proximal quarter black, but black stopping short of anterior margin. 
(8) Specimen about 30 ft. long—Al|most entirely black on the under side of 
body; pectorals white below, and only black above a little distance from proximal end. 
Cocks gives additional notes on specimens captured in 1885, as follows (17, 
4 sep.): 
(1) Male, about 35 ft. long —Knutirely black on under side of the body except 
a not clearly-defined patch of white near each point of the under side of the flukes ; 
some very small spots of white on chin and belly (due to barnacles). Pectorals all 
white below; above, black for a very short distance at the proximal end, 
(2) Specimen 44 ft. long.—Pectorals above with the proximal quarter black, 
the black extending down the anterior edge, with a few small irregular black 
marks lower down. 
(8) Male, 42 ft. long.— Entirely black on the belly, but nearly the whole 
chest and throat white; chin black, with a few small white flecks. Furrows on 
the belly light purplish flesh-color. A small white streak on the upper lip. Very 
little black on the outside of the pectorals, including a narrow rim along the 
hinder margin. 
(4) Small male.—Chin black; some white on lower jaw; throat and chest 
white as far as posterior end of furrows; remainder of under side black. 
Struthers’s notes on the color of the Humpback obtained in the Tay River, 
Scotland, in 1883, give the following points (87): All black, except the snow- 
white under surface of the flukes and pectorals, and certain spots and streaks of 
white about the navel and genital orifice. (Color of the upper surface of the 
pectoral uncertain. ) 
Sars, describing the Finmark Humpback (80, 14), states that the color on the 
head and lower jaw is black, in the middle of the throat and breast, white, and 
elsewhere on the parts variegated white and black, with rings and spots. The 
back, sides, and the whole of the body behind the middle, black. Pectorals white 
on both sides throughout, sharply defined from the black color of the body, but 
with an ill-defined dark shading on the upper surface at the base. Flukes black 
above and below, with white rings along the posterior border, on both surfaces, but 
more numerous below. 
Rawitz furnishes the following data relative to the color of the four Hump- 
backs examined by him at Bear Id. in 1899 (74, 74): 
Male ; length, 12.7 m.—Back and sides black. Tip of mandible black, with 
lighter places only here and there about its base. The knot-like projection on the 
throat also black, but with linear transverse white flecks anteriorly. From the 
projection to the line of the corner of the mouth the color is almost entirely white, 
stretching only half as far back on the left side as on the right. Middle of throat
